Specification of Letters Patent.

Application filed August 11, 1916. Serial No. 114,453.

To all whom it may concern:

Be it known that I, Anonzo J. BRIDGES, a citizen of the United States, residing at Bedford, in the county of Taylor and State of Iowa, have invented certain new and useful Improvements in Filters, of which the following is a specification.

This invention relates to a filter and more particularly to the class of filters designed for cleansing and purifying cistern water and adapted to remove the finest particles of dirt or silt from the water.

One of the objects of the invention is to provide a filter of this character for straining the coarse refuse in one chamber and providing a sub-chamber having additional straining elements for removing finer particles of refuse from the water and com-- pleting the operation by providing a bed of charcoal through which the water passes for purifying the same.

Another object of the invention is the provision of a deflecting plate disposed directly beneath the conductor pipe whereby the water, as it passes into the filter, will be diverted and spread evenly over the first strainer element so that the whole surface of the strainer element will be employed for receiving the refuse.

A further object of this invention is the provision of a filter which consists of com paratively few parts and is simple in construction, but durable and well adapted to withstand the rough usage to which devices of this character are ordinarily subjected.

For a full description of the invention and the advantages and merits thereof, reference is to be had to the following description and the accompanying drawings, wherein is illustrated the preferred form ofmy invention, in which Figure 1 is a perspective view of the filter.

Fig. 2 is a vertical longitudinal section therethrough.

Fig. 3 is a fragmentary horizontal section on the line 3-3 of Fig. 2.

Referring to the drawings, wherein is illustrated the preferred form of my invention, and in which like numerals of refer ence indicate corresponding parts throughout the several views, the device comprises a single container divided into a plurality of various chambers for performing difierent functions. The uppermost strainer chamber 1 is provided in its top wall with an opening 2 having an inlet pipe 3 attached to and communicating with the opening. This pipe 3 is designed to receive one end of a conductor pipe (not shown) whereby the rain water or other water to be filtered, may be conducted into the first strainer chamber 1. It will be noted that the top wall of the strainer chamber 1 is extended so that it projects beyond the end wall of the main container and the end wall 4 of the chamber 1 is curved downwardly and inwardly until it joins the end wall 5 of the main container. The curve in the wall 4. is thereby disposed directly beneath the center of the conductor pipe and when the water rushes into the first strainer chamber 1 it strikes the curve in the Wall 4: and is de fiected so that it spreads evenly over the foraminous partition 6 arranged in the bottom of the strainer chamber 1. The opposite end of the strainer chamber 1 is provided with an opening 7 through which the bits of straw, leaves and other similar refuse is ejected from the chamber by the force of the water passing over the screen or foraminous partition 6. The partition 6 is composed of a rectangular frame 8 adapted to rest upon a shelf 9 mounted within the main container and this frame 8 supports a relatively coarse wire mesh for forming the foraminous partition. The largest particles of refuse are thereby effectively stopped by the partition 6 and are ejected through the opening 7 by the force of the water as it is deflected from the curved end wall 1 thereby obviating the possibility of a quantity of refuse collecting on the screen 6.

A second strainer chamber 10 is formed in the main container by providing a shelf 11 upon which is mounted a tray 12 formed of foraminous material, preferably of a finer mesh than that employed in constructing the partition 6. The bottom tray 12 extends completely across the bottom of the second strainer chamber 10 and is provided with the relatively narrow walls of the same material. An auxiliary strainer element 13 formed of cheesecloth or other suitable similar fabric is employed in connection with the strainer 12 and, as clearly shown by Fig. 2 of the drawing, is disposed within the tray so that it forms a lining therefor and has its marginal edge hanging over the side walls of the tray. The water must pass through both the auxiliary strainer 13 and the strainer tray 12 and, since it is of a finer mesh than the partition 6, the finer particles of dirt and silt will be retained in the second strainer chamber.

As shown by Fig. 1 of the drawing, the lower portion of the main container is increased in width below the first strainer chamber 1 and one side is provided with a curved cover 14; which is fitted over the open side of the second strainer chamber 10. Hinges 15 connect the door 14 with the side of the first strainer chamber so 'that the cover 14 may be lifted for removing the foraminous tray 12 from the second strainer chamber when it is desired to clean the same.

Below the second strainer chamber 10 the main container is divided by a vertical transverse partition 16 into a main compartment 17 and a relatively narrow compartment 18. The partition 16, as clearly shown by Fig. 3 of the drawing, is connected to the side walls of the main container and its upper end is bent to extend over the top of the compartment 18 to provide a top wall 19 therefor. The lower edge of the partition 16 terminates slightly above the bottom of the main container to provide the space 20 which acts as a passage way for permitting the water to pass from the main compartment 17 into the compartment 18. Arranged in the space 20 is a screen 21 of foraminous material. Packed within the main compartment 17 is a bed of charcoal which receives the water when it passes through the screen at the bottom of the second container chamber 10. Charcoal, by virtue of the great oxygen retaining power which it possesses, is one of the best agencies employed for puri fying water. The effect of the oxygen upon the water is to destroy and exterminate foreign particles and thereby render the water palatable. While the two first mentioned strainer elements remove the refuse and debris from the water, it remains for the charcoal to clarify the same so that it is ren dered palatable and free from any impurities that would be liable to cause diseases. The screen 21 in the opening 20 prevents the charcoal from passing into the chamber 18 and this chamber, therefore, is entirely clear at all times for receiving the purified water.

Arranged upon the end of the main container mid-way between the top and bottom of the end wall of the main container is an ejecting chamber 22 and an opening 23 in the end wall of the container permits the purified water to pass from the compartment 18 into the ejecting chamber 22. A curved cover 2 1 is hingedly connected to the end wall 5 of the container and covers the ejecting chamber 22. Depending from the lower bottom wall of the ejecting chamber is a spout 25 whereby the water may be dis charged in a suitable receptacle.

A screen covering 26 is arranged on the bottom of the container and covers the opening which establishes communication between the interior of the ejecting chamber and the spout 25. This chamber may be also used for cooling the filtered water since pieces of ice may be placed within the chamber so that the water will flow over the ice before it passes through the spout 25.

An opening in the bottom of the main container is closed by a screw cap 26 and this cap may be removed when it is desired to drain the water which has settled in the bottom of the main container when the water has stopped circulating through the charcoal. It is pointed out that the structure provides easy access to all of the screens within the container and they may be easily and quickly removed without disturbing each other.

From the foregoing it will be observed that a very simple and durable filter has been provided, the details of which embody the preferred form. I desire it to be under stood however, that slight changes in the minor details of construction may be made without departing from the spirit of the invention or the scope of the claims hereunto appended.
